@hm: There have probably been about 6 times in the last 30 years that I've worn them -- but each time the snow was deep (more than 8 or 9 inches) and the weather was FREEZING ... and no one was laughing at them then ... everyone was saying "where can I get a pair of boots like that?" (grin)
In fact I still have mine more than 30 years later -- I'm just waiting for it to snow enough to warrent wearing them (I live in Huntsville, Alabama, USA, so we typically only get 1 to 2 inches (if we get any at all)
I too purchased a pair of moon boots when touring thru the ski fields one year on a motor bike as they made excellent over-boots. For someone from closer to the equator it was bitterly cold. I returned to the tropics and as they were completely unheard of they were rather novel... One night kids broke into the house, stepped over the expensive cameras and computers, knocked off the loose change and... yep, the somewhat rare moon boots.
